Application meu March 29, 1921. sefiai`1tu145e66s- To all whom t may concern-1 citizen of the United States, residing in the cityof Newark, countyofEsseX, andi State 5 of New Jersey, and OTTO BUCHHOLZ, af citi/- zen of the United States, residing inf the city of Elizabeth, in the countyfof Union and State of New Jersey, haveI invented'certain new and'useful Improvements in Tube-Fill- 11.0 ing Apparatus, of which 'the following is a specication.v n M l The main purpose ofthis invention is fito provide' an a1g paratusy for filling collapsible or du'ctile tubes with pastes, and llike plastic i5 substances, in a clean,effective and speedy manner. f i f f i A further object is to provide means combined with the device,- for closing and clinch- 4ing the open end of the yfilled tube readyfor use inthe'usual way; 4 Y Y A stillfurther obj ect is toprovide; an apparatus particularlyfforxthe use of individ` ual druggists, enabling them :to prepare and e dispense prescriptions' for ointments and pastes in an approved and'sfanitaryfforin, the

entire structure being easily" operated, of relatively low expensev to construct yandin'ot readily.'l iabletov derangeinent.

These and like other' ob'ects are Aattained 30 by the novel construction, combination and,v

arrangement of parts hereinafter described vand shown in the accompanying drawings,

. A bushing preferably formed ofsecti'ons A 26gand 26 forl enabling the operator to,

easilyr the saniewith 'the substance tobe so f entered kinto ythe collapsible tube, is entered into the sleeve 20, the outer end of the bushing, either split or solid, abutting against the tace of the disc 2Q.

A piston or plunger 28 is slidably and removably fitted to the interior of the? bushing and is forced forward by means of the end of a stein 29, having a fork 3l) at its outer end, this fork being pivotally secured to a link h'coi'iiiect'ing wit-ha lever 32. i

This lever 32 is pivoted on a screw S3 set in an extension of the base and is pro-V videdwith an extending operating handle 34k for manually moving the saine. v

The lever rides freely overa raised ridge 35 on the trent of the base and a xed stop 36 in the base limits its outward motion.

blocks() isset in the base l5', adjacent 9; ver iiulcrum screw 33, the block being held in position by screws il to present a flat angular tace l2 so positionedy that the adjacent edge oi'` the lever 32 can inake iiitimate contact with it. y

ln operation, the lever is moved outwardly, permitting the sleeve, nozzle, vand bushing to be raised as aunit from its channelled seat7 the bushing withdrawing l'rom the sleeve and lilled, either partially orwholly with .any desired .medicament, this being easily accomplished by separating the bushing, after which the parts are replaced, with the removable piston kor plunger inserted in the end of the bushing.

The collapsibletube isapplied byhand so that itsopen end. opposite theI closure or cap is entered over the nipple, the piston directed to enter the bushing and the handlepulled outwardly towards the front, causing the medicament to be extruded` through the opening in the discdirectly intothe tube until it is lled to the desired capacity.

After removing the tube it is held, bottom downward, ladjacent the flat face of the block and pressure applied yby actuating the lever in an obvious mannen p While certain preferred embodiments oit this device have been shown and described, it will be understood thatchanges in the form, ,arrangeinentsv7 .proportions7 sizes and details thereof may be made without de'- parting from the scope otthe'invention dened in the appended claims. v

yThe parts oit the apparatus, namely,pthe sleeve 20, the sections 26 andA 26', the piston 28 and the stem 29 together with the disc 22 'and its'attacl'ied nipple 23, lend themselves readily to be kept in 'a clean and sanitaryv condition; The piston being removable and separate fromthe stem, there are no sharp corners or joints which cannot be kept in a clean and sanitaryl condition.

Having thus described our invention,what we desire to secure by Letters Patent and l. An, apparatus for Filling collapsible tubes, comprising a base, an open socket itoiined at the front thereof, an annular sleeve removably engaged in said socket, a nozzle detachably secured insaid sleeve, a cylindrical split bushing contained in said sleeve abutting said nozzle, a removable piston in said bushing, 'a manually operated lever pivoted on said base, and linked connections between said lever and said piston.
